Coumarin induced root formation and stimulated fresh weight production in hypocotyl explants of Glycine max L. cultured in vitro . All stimulatory effects caused by coumarin were induced within a relatively narrow range of concentrations between 1–500 μ M , yielding optimum dose response curves. When coumarin was combined with kinetin fresh weight increased considerably, at optimum concentrations to a level almost as high as that obtained with NAA (10 μ M ) and kinetin (10 μ M ). Root formation was almost completely inhibited when kinetin was added in combination with coumarin. NAA + coumarin had small stimulatory effects on fresh weight. but were inhibitory in root formation. The frequency of rooting per explant, texture and pigmentation were also affected by different treatments.
